maybe it just depends on what you mean by “a natural weight”. it seems like what it’s come to mean is, given access to as much processed food you want of the type you’d want, and given the option to exercise or move as much or as little as you’d like, what would you “naturally” do. i would suggets that there sis no way to view any of those states is “natural” in any meaningful kinda way and any weight assicated with this bountiful state of affairs cannot in any way said to be natural or inevitable.
